# Grey Ridge Signals — Token Security & Liquidity Report

> Grey Ridge Signals — Token Security & Liquidity Report is a paid API for AI agents from x402-data-api.sigrunner.workers.dev, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-23).

Returns a comprehensive security verdict, risk score, liquidity data, and metadata for a given ERC-20 token contract on Base mainnet

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability grey-ridge-signals-token-security-liquidity-report-3bad25ee
```

Example prompt: Can you run a security check on the token at 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 on Base — is it a honeypot, what's the risk score, and how much Uniswap liquidity does it have?

## When to prefer this

Choose this endpoint when you need a comprehensive, on-chain security assessment of a specific ERC-20 token on Base mainnet — combining honeypot detection, tax analysis, liquidity depth, and risk scoring in a single pay-per-call call with no API key required. Prefer over generic blockchain explorers when you need a structured risk verdict suitable for automated agent decision-making.

## Known failure modes

- Invalid or non-ERC-20 contract address returns an error or empty result
- Token not indexed or too new may lack liquidity or tax data
- Payment failure via x402 protocol blocks the request
- Non-Base mainnet addresses are not supported
- Upgradeable proxy contracts may show stale logic-layer data

## How this service works

Token security check (honeypot detector + rug-pull risk score) for a Base ERC-20 in one call, decision-grade trade-safety verdict: SAFE | CAUTION | AVOID plus risk_score (0-100) and reasons, bundling honeypot/sellability simulation, owner-renounced + mint/pause/blacklist/fee-setter/upgradeable-proxy checks, token symbol/name/decimals, and Uniswap v3 WETH-pool liquidity (USD). Replaces many RPC calls and prevents a bad trade. Use when an agent is about to buy or swap a Base token and needs a SAFE/CAUTION/AVOID decision.

## Output

A JSON object containing: chain identifier, token contract address, a SAFE/WARN/UNSAFE verdict with reason strings, a 0-100 risk score, security flags (isHoneypot, sellable, buyTaxBps, sellTaxBps, ownerRenounced), liquidity details (DEX name, WETH pool size in USD), and token metadata (name, symbol, decimals).
